The time travel was lacking in understanding of planetary drift has the earth has change in orbit field around the sun and rotational speed over millions of years so them endding up in the same place each time was highly unrealistic without a quatum computer doing the math with a senor to track spacial displacement in exterior of temporal area. Also the plothole when at tome buildings where pulled threw and outer times not like the Indian grave where knowing has it Contradicted what chacthers sayed about how it the time area toke what with it. I can’t say I hated but lived just injoyed the read with nice references to outer novels like the outer or how this linked to a later release by you “Exo hunters” there where the times I think you where referencing The Sigma Force novels by James Rollins or novels by JC Ryan.
